Amyloidose der Herzklappen beim Hund

Abstract
Histological examination of 80 dogs with endocardiosis showed five cases of amyloidosis of the heart valves. The diagnosis was based on positive reactions of several stains and histochemical tests and the demonstration of a characteristic fibrillar structure in the amyloid deposits with the electron microscope. The possible pathogenetic relationship of valvular amyloidosis to endocardiosis in aging dogs is discussed.
